Method for controlling operation of a lighting system having high intensity narrow spectrum light sources

A lighting system, comprising:

• one or more first light sources configured to emit high intensity narrow spectrum (HINS) light;
• one or more second light sources configured to emit at least non-HINS light;
• and
• one or more control devices configured to:
• operate the lighting system in a first mode to provide a first light output during a time period, the first light output comprising a blend of the HINS light emitted from the one or more first light sources and non-HINS light emitted from the one or more second light sources;
• determine a dosage amount of HINS light provided during the time period;
• operate the lighting system in a second mode to provide a second light output based, at least in part, on the dosage amount, the second light output comprising HINS light or a blend of HINS light and non-HINS light,
• wherein spectral energy associated with HINS light in the second light output is greater than spectral energy associated with the HINS light in the first light output;
• determining, by the one or more control devices, a difference between the dosage amount and a threshold dosage amount;
• and
• determining, by the one or more control devices, a duration to provide the second light output based, at least in part, on the difference between the dosage amount and the threshold amount.
